Wireless-G IP Phone
Product Usage Restrictions
This product is designed for indoor usage only. Outdoor usage is not recommended, unless otherwise noted.
2,4 GHz Restrictions
This product is designed for use with the standard, integral or dedicated (external) antenna(s) that is/are shipped together with
the equipment. However, some applications may require the antenna(s), if removable, to be separated from the product and
installed remotely from the device by using extension cables. For these applications, Linksys offers an R-SMA extension cable
(AC9SMA) and an R-TNC extension cable (AC9TNC). Both of these cables are 9 meters long and have a cable loss (attenuation)
of 5 dB. To compensate for the attenuation, Linksys also offers higher gain antennas, the HGA7S (with R-SMA connector) and
HGA7T (with R-TNC connector). These antennas have a gain of 7 dBi and may only be used with either the R-SMA or R-TNC
extension cable.
Combinations of extension cables and antennas resulting in a radiated power level exceeding 100 mW EIRP are illegal.
